hmm... i just made this patch find D-state used for suspend:
+ /*
+ * Some systems crash if an EHCI controller is in D3 during
+ * a sleep transition. We have to leave such controllers in D0.
+ */
+ if (hcd->broken_pci_sleep) {
+ retval = pci_prepare_to_sleep(pci_dev);
+ printk("TTTTT, %i\n", retval);
+ dev_dbg(dev, "Staying in PCI D0\n");
+ return retval;
+ }
but system freezed. Same way like before, with memory corruption. It looks like
pci_prepare_to_sleep() is the cause of this issue.
